Hassan Hassan writes: Before Fayad Tayih abandoned the Islamic State earlier this month, he detected a striking trend: More people inside the self-declared caliphate were signing up to become suicide bombers. Mr. Tayih had been working in an administrative job for the jihadist group in Deir al-Zour, in eastern Syria, at the time. “Those who were working with me noticed the same thing,” he told me over Wickr, an encrypted messaging app.

Statistics released by the Islamic State confirm his observations.

The group is reverting to insurgency tactics it relied on before June 2014, when it took over Iraq’s second-largest city, Mosul, and declared the formation of a caliphate. This operational change has been on plain display in recent weeks: Hundreds of civilians were killed in a spate of suicide attacks attributed to the Islamic State in Turkey, Iraq, Bangladesh and Saudi Arabia. In Baghdad last week, more than 280 civilians were killed when a car bomb exploded outside a shopping mall.

Some people have suggested that this is a sign of the group’s desperation and weakness. In fact, it demonstrates its strength and long-term survival skills.

In “The Management of Savagery,” a foundational text for the Islamic State’s ideology and strategy published in 2004, the author pointed out that in the 12th century, Muslims defeated the Crusaders with “small bands” and “separate, disparate organizations.” The group has not forgotten that message.
